About

CallSine is an autonomous, agent-powered outreach and sales-engagement platform that researches prospects deeply, scraping websites, LinkedIn profiles, and company information, to deliver hyper-personalized messaging at scale. It uses a multi-agent pipeline built on retrieval-augmented generation to ingest your sales and marketing assets, understand your value proposition, generate individualized emails, LinkedIn messages, or calls, and orchestrate deployment across channels with timing and cadence tailored to each prospect. CallSine doesn’t rely on basic templating; instead, it builds context-rich outreach by combining deep prospect insight, branded content, and automated follow-ups driven by behavioral cues. It also provides analytics and AI coaching to monitor engagement, refine messaging, and adapt strategy based on responses or lack thereof.

About

Starnus is an AI-powered business automation platform that functions like a virtual employee, enabling teams to delegate complex workflows through simple natural-language instructions. Instead of producing one-off outputs, the system converts a defined objective into a structured plan and executes it autonomously across connected tools while continuously monitoring progress and iterating until the goal is achieved. It coordinates multiple specialized AI agents that collaborate to handle tasks such as outbound sales, lead generation, inbox management, CRM updates, research, reporting, and operational workflows. Users describe the job in plain language, and Starnus clarifies requirements, selects the appropriate agents, and manages execution end-to-end, reducing the need for manual orchestration. It is designed to operate for extended periods, handling edge cases, retrying failed steps, and improving workflows over time to deliver measurable outcomes.
